I have Genie 2 2019.2 and it has the 6.1 firmware for my OPN 1 miniRITE.
It may have newer firmware versions for the OPN S, but for the OPN 1 miniRITE, it is 6.1.
I just did a “check update” on my Genie software install and it says that there’s no new update found.
But for the last several versions of Genie 2, I usually heard about a newer Genie 2 version before the update was made available on the official site, so I had to download the early release version from whatever site they became available early on. The 2019.2 was downloaded from the Oticon UK site. The version before that was from the Oticon Canada site. The Oticon USA site tends to release it later than the other sites from abroad.
